mapRange method

double mapRange({ required double fromMin, required double fromMax, required double toMin, required double toMax, })

Maps this value from one range fromMin, fromMax to another toMin, toMax.

Example:

double value = 50.0;
double mapped = value.mapRange(fromMin: 0.0, fromMax: 100.0, toMin: 0.0, toMax: 1.0); // 0.5

Implementation

double mapRange({
  required double fromMin,
  required double fromMax,
  required double toMin,
  required double toMax,
}) {
  if (fromMax == fromMin) return toMin;
  final normalized = (this - fromMin) / (fromMax - fromMin);
  return toMin + normalized * (toMax - toMin);
}
